Description

Technical Field

[0001] This utility model relates to an electronic lock and a charging dock including the electronic lock. Background Technology

[0002] In existing technology, new energy electric vehicles are equipped with a charging socket for mates with a charging gun to charge the vehicle's battery. To prevent the charging gun from accidentally separating from the charging socket during charging, an electronic lock is usually installed on the charging socket. The electronic lock functions to lock the charging gun during vehicle charging and to send a signal to the vehicle that the charging gun is locked. Typically, the electronic lock has a locking pin that can move between a locked position and an unlocked position. When the locking pin is moved to the locked position, it engages with a pin hole on the charging gun to lock the charging gun to the charging socket; when the locking pin is moved to the unlocked position, it disengages from the pin hole on the charging gun, allowing the charging gun to be removed from the charging socket.

[0003] In the use of existing electronic locks, the locking pin may be disengaged from its locking position due to the charging gun being tilted and touching the head of the locking pin, or other external forces accidentally touching the head of the locking pin. This can cause the electronic lock to mislock, resulting in the electronic lock being unable to reliably lock the charging gun to the charging base, and there is a risk that the charging gun will detach from the charging base.

[0017] According to another exemplary embodiment of the present invention, the lock housing has a front end and a rear end opposite each other in its longitudinal direction. The output member is movable along the longitudinal direction between a first extreme position and a second extreme position located in front of the first extreme position, thereby driving the locking pin to move between the unlocked position and the locked position. The output member has a receiving groove, and the front end of the unlocking rod has a stepped portion, which is received in the receiving groove. When the output member moves between the first extreme position and the second extreme position under the drive of the motor, the unlocking rod is not engaged with the output member; when the motor does not output power, the unlocking rod can move backward under user operation, so that the rear end face of the stepped portion abuts against the rear wall of the receiving groove, thereby driving the output member to move backward to the first extreme position and driving the locking pin to move to the unlocked position.

However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated to simplify the figures.

[0029] According to a general technical concept of this utility model, an electronic lock is provided. The electronic lock includes: a lock housing; a locking pin extending from the lock housing and movable between an unlocked position and a locked position; a drive device installed in the lock housing for driving the locking pin to move; and a backstop transmission device tractively connected between the drive device and the locking pin, such that when the drive device outputs a driving force to the backstop transmission device, the backstop transmission device can drive the locking pin to move between the unlocked position and the locked position, and when the locking pin is in the locked position and the drive device does not output a driving force, the backstop transmission device can hold the locking pin in the locked position.

[0030] According to another general technical concept of this utility model, a charging dock is provided. The charging dock includes: a housing; a charging terminal disposed in the housing for mating with a mating terminal of a charging gun inserted into the housing; and the aforementioned electronic lock, fixedly installed to the housing. When the locking pin is moved to the locked position, the locking pin is adapted to engage with a pin hole on the charging gun to lock the charging gun to the charging dock; when the locking pin is moved to the unlocked position, the locking pin disengages from the pin hole on the charging gun to allow the charging gun to be pulled out of the charging dock.

Figure 7 Showing a cross-sectional view of an electronic lock according to an exemplary embodiment of the present invention; Figure 8 Showing a longitudinal sectional view of an electronic lock according to an exemplary embodiment of the present invention, wherein the locking pin 2 is in the unlocked position; Figure 9 This shows a longitudinal sectional view of an electronic lock according to an exemplary embodiment of the present invention, wherein the locking pin 2 is in the locked position.

[0032] like Figures 1 to 9 As shown, in an exemplary embodiment of this utility model, an electronic lock is disclosed. The electronic lock mainly includes a lock housing 1, a locking pin 2, a drive device 3, and a backstop transmission device 4.

[0033] The lock housing 1 includes a main housing 11 and a top cover 12 connected to the top of the main housing 11. A locking pin 2 extends from the lock housing 1 through a through-hole in the top cover 12 and can be positioned in the unlocked position (e.g., ...). Figure 8 (as shown) and locking position (as shown) Figure 9 The lock pin 2 moves between the lock housing 1 and the lock housing 1. The drive unit 3 is installed in the lock housing 1 and is used to drive the locking pin 2 to move.

[0034] The anti-reverse transmission device 4 is connected between the drive device 3 and the locking pin 2, so that when the drive device 3 outputs driving force to the anti-reverse transmission device 4, the anti-reverse transmission device 4 can drive the locking pin 2 to move between the unlocked position and the locked position. When the locking pin 2 is in the locked position and the drive device 3 does not output driving force, the anti-reverse transmission device 4 can keep the locking pin 2 in the locked position (see the following description) to avoid accidental locking due to the part of the locking pin 2 protruding from the lock housing 1 being accidentally touched by external force.

[0035] This electronic lock is used, for example, in a vehicle charging dock (not shown). When the locking pin 2 is moved to the locked position, it is adapted to engage with a pin hole (not shown) on the charging gun (not shown) to lock the charging gun to the charging dock. When the locking pin 2 is moved to the unlocked position, it disengages from the pin hole on the charging gun to allow the charging gun to be removed from the charging dock.

[0036] The drive unit 3 includes an output component 31, which is connected to the anti-reverse transmission device 4 and is capable of operating at a first extreme position (e.g., Figure 8 (as shown) and second extreme positions (as shown) Figure 9 The device moves between the positions shown in the diagram to drive the anti-reverse transmission device 4 to the initial position (as shown in the diagram). Figure 8 (as shown) and holding position (as shown) Figure 9 As shown, the locking pin 2 moves between the lock housing 1 and the lock housing 1 in the height direction Z, thereby causing the locking pin 2 to move to the unlocked position (as shown). Figure 8 (as shown) and the locking position that extends further upward from the lock case 1 (as shown) Figure 9 Move between (as shown).

[0037] The lock housing 1 has a front end and a rear end opposite each other in its longitudinal direction Y, and the output member 31 is movable in the longitudinal direction Y between a first extreme position and a second extreme position located in front of the first extreme position.

[0038] The lock housing 1 is provided with a limiting part 13, which is used to stop the output member 31 when it is in the second extreme position. When the output member 31 is in the second extreme position, the locking pin 2 is in the locked position, the anti-reverse transmission device 4 is in the holding position, and can apply a pushing force toward the limiting part 13 to the output member 31 in response to the downward pushing force on the locking pin 2, that is, a forward pushing force (see below for details), so that the output member 31 abuts against the limiting part 13 and does not move forward or backward, thereby keeping the locking pin 2 in the locked position.

[0039] In the illustrated embodiment, the limiting part 13 is integrally formed on the front wall 111 of the lock housing 1. However, the present invention is not limited to the illustrated embodiment. For example, the limiting part 13 may also be formed on the bottom wall 112 of the lock housing 1, or the limiting part 13 may also be provided by another component connected to the lock housing 1.

[0040] See also Figures 1 to 9 In the illustrated embodiment, the electronic lock further includes a movable base 5, which is movably mounted in the lock housing 1. A locking pin 2 is fixedly connected to the movable base 5 and connected via the movable base 5 to the anti-reverse transmission device 4.

[0041] The anti-reverse transmission device 4 includes a transmission rod 40, which includes a movable seat pivot portion 401 and an output member pivot portion 402 located at both ends along its length. The movable seat pivot portion 401 is rotatably connected to the movable seat 5 about a first axis 403, and the output member pivot portion 402 is rotatably connected to the output member 31 about a second axis 404. The first axis 403 and the second axis 404 extend along the transverse X direction of the lock housing 1, respectively.

[0042] In the illustrated embodiment, the movable seat pivot portion 401 and the output member pivot portion 402 each have cylindrical protrusions. These cylindrical protrusions are inserted into corresponding cylindrical holes in the movable seat 5 and the output member 31, respectively, to rotatably connect the movable seat pivot portion 401 and the output member pivot portion 402 to the movable seat 5 and the output member 31, respectively. However, this invention is not limited to the illustrated embodiment. In other embodiments not illustrated, the movable seat pivot portion 401 and the output member pivot portion 402 can also be rotatably connected to the movable seat 5 and the output member 31 in other ways.

[0043] like Figure 8 As shown, when the anti-reverse transmission device 4 is in the initial position, the movable seat pivot 401 is located in front of and above the output member pivot 402. Therefore, when the output member 31 moves forward along the longitudinal direction Y from the first extreme position, the transmission rod 40 can rotate and translate clockwise under the drive of the output member 31, and drive the movable seat 5 and locking pin 2 to move upward along the height direction Z until they reach the desired position. Figure 9 The state shown.

[0044] like Figure 8 As shown, when the anti-reverse transmission device 4 is in the initial position, the angle between the perpendicular segment 405 between the first axis 403 and the second axis 404 and the longitudinal direction Y is not less than 45°, so that the forward thrust of the output component 31 on the transmission rod 40 can be better converted into the torque that makes the transmission rod 40 rotate, thus making it easy to drive the transmission rod 40 to move through the output component 31, and thus making it easy to drive the moving seat 5 and the locking pin 2 to move along the height direction Z.

[0045] like Figure 9 As shown, when the anti-reverse transmission device 4 is in the holding position, the movable seat pivot 401 is located behind and above the output member pivot 402. Therefore, when the locking pin 2 is accidentally struck by a downward or tilted downward external force in its locked position, the locking pin 2 exerts a downward thrust on the transmission rod 40 of the anti-reverse transmission device 4 via the movable seat 5, thereby generating a torque that causes the transmission rod 40 to rotate clockwise, and further causing the transmission rod 40 to exert a forward thrust on the output member 31. However, since the front end of the output member 31 is stopped by the limiting part 13 and cannot move forward, the transmission rod 40 cannot rotate or translate, thus keeping the locking pin 2 in the locked position.

[0046] In the illustrated embodiment, the anti-reverse transmission device 4 includes a pair of transmission rods 40 arranged at a transverse X-interval. In other embodiments not illustrated, the anti-reverse transmission device 4 may also include one or more than two transmission rods 40.

[0047] See also Figures 1 to 9 In the illustrated embodiment, the lock housing 1 is further provided with an output guide 14, which cooperates with the output member 31 to guide the output member 31 to move along the longitudinal direction Y.

[0048] Specifically, the output guide 14 includes a guide bar 141 extending longitudinally along the Y direction formed on the bottom wall 112 of the main housing 11 and a first vertical wall 121 formed on the top cover 12. A guide groove 312 extending longitudinally along the Y direction is formed at the bottom of the output member 31, and the guide bar 141 movably engages with the guide groove 312. The lower surface of the first vertical wall 121 extends longitudinally along the Y direction and movably engages with the upper surface of the output member 31 extending longitudinally along the Y direction.

[0049] Additionally or alternatively, the output guide 14 also includes a bottom wall 112, a side wall 113, and a second vertical wall 114 formed in the main housing 11. The bottom wall 112 is movably engaged with the bottom surface of the output member 31, and the side wall 113 and the second vertical wall 114 are respectively movably engaged with the surfaces on both sides of the output member 31 in the transverse X direction in the longitudinal Y direction.

[0050] Thus, the output guide 14 cooperates with multiple parts of the output member 31 to guide the output member 31 to move longitudinally Y and restrict the rotation of the output member 31 as well as its movement in the transverse X and vertical Z directions.

[0051] like Figure 2 and Figure 6 As shown, the lock housing 1 is also provided with a movable seat guide 15, which cooperates with the movable seat 5 to guide the movable seat 5 to move along the height direction Z.

[0052] Specifically, the movable seat guide 15 includes a plurality of vertical walls extending along the height direction Z disposed in the main housing 11. These vertical walls engage with a plurality of surfaces on the front and rear sides and left and right sides of the movable seat 5 in a manner movably along the height direction Z to guide the movable seat 5 to move along the height direction Z and to restrict the rotation of the movable seat 5 as well as its movement along the lateral X and longitudinal Y directions.

[0053] See also Figures 1 to 9 The drive unit 3 mainly includes a motor 30, an output component 31, and an unlocking lever 32. The motor 30 is fixedly connected to the lock housing 1 and provides power to drive the locking pin 2 to move between the unlocked and locked positions. The output component 31 connects the motor 30 and the anti-reverse transmission device 4 to transmit the power output by the motor 30 to the anti-reverse transmission device 4. The unlocking lever 32 is movably connected to the lock housing 1 and drives the locking pin 2 to move to the unlocked position when the motor 30 is not outputting power.

[0054] like Figure 8 and Figure 9 As shown, when the locking pin 2 moves under the drive of the motor 30, the unlocking lever 32 remains stationary relative to the lock housing 1, maintaining a position easily operable by the user. When the motor 30 is not outputting power, the unlocking lever 32 can move under user operation and engage with the output component 31, thereby moving the locking pin 2 to the unlocked position. Thus, in the event of a power outage, motor 30 malfunction, signal transmission failure, or other abnormal or emergency situations, the locking pin 2 can be manually reset to the unlocked position, detached from the charging gun.

[0055] The output component 31 has a receiving groove 310 extending along the longitudinal direction Y, and the front end of the unlocking lever 32 has a stepped portion 321, which is received in the receiving groove 310.

[0056] like Figure 5 , Figure 8 and Figure 9 As shown, when the output component 31 moves between the first limit position and the second limit position under the drive of the motor 30, the unlocking lever 32 does not engage with the output component 31 and thus does not move with the output component 31, so as to remain in a position that is convenient for user operation.

[0057] When the motor 30 does not output power, the unlocking lever 32 can move backward under the user's operation, so that the rear end face 321a of the step portion 321 abuts against the rear wall 310a of the receiving groove 310, thereby driving the output component 31 to move backward to the first limit position, and driving the transmission rod 40 of the anti-reverse transmission device 4 to rotate counterclockwise and translate, so that the anti-reverse transmission device 4 moves to the initial position, and drives the locking pin 2 to move to the unlock position.

[0058] In some other embodiments not shown, the rear end face 321a of the step portion 321 of the unlocking lever 32 may abut against the rear wall 310a of the receiving groove 310 when the output member 31 reaches the second limit position driven by the motor 30.

[0059] See also Figures 1 to 9 An operating hole 16 is formed on the rear side of the lock case 1, which connects the interior and exterior of the lock case 1. The rear end of the unlocking lever 32 is inserted into the operating hole 16 so that the user (e.g., by inserting a tool into the operating hole 16) can operate the unlocking lever 32.

[0060] However, the present invention is not limited to the embodiments shown in the figure. For example, in some other embodiments not shown in the figure, the rear end of the unlocking rod 32 may not be inserted into the operation hole 16, but may be located in front of the operation hole 16 and opposite to the operation hole 16.

[0061] See also Figures 1 to 9 The lock housing 1 is provided with an unlocking rod guide 17, which cooperates with the unlocking rod 32 to guide the unlocking rod 32 to move along the longitudinal Y direction.

[0062] Specifically, the unlocking lever guide 17 includes a base 171 extending longitudinally Y on the bottom wall 112 of the main housing 11 and a top wall 310b of the receiving groove 310. The unlocking lever 32 includes a front section 322 that movably extends into the receiving groove 310 of the output member 31, with stepped portions 321 formed on opposite sides of the front section 322 in the transverse X direction. The front section 322 has an upper surface 322a and a lower surface 322b opposite to each other in the height direction Z. The upper surface 322a is formed as a curved surface extending longitudinally Y and convex upward, and the lower surface 322b is formed as a curved surface extending longitudinally Y and convex downward. The top wall 310b of the receiving groove 310 is formed as a curved surface extending longitudinally Y and concave upward, and movably engages with the upper surface 322a of the front section 322. The top surface of the base 171 is formed as a curved surface that extends longitudinally Y and is recessed downward, and it movably engages with the lower surface 322b of the front section 322.

[0063] Thus, the unlocking lever guide 17 cooperates with the unlocking lever 32 to guide the unlocking lever 32 to move longitudinally Y, and restricts the rotation of the unlocking lever 32 as well as its movement in the lateral X and vertical Z directions.

[0064] The drive unit 3 also includes a gear transmission mechanism 33. The gear transmission mechanism 33 is connected between the output shaft 301 of the motor 30 and the output component 31, and is used to convert the rotational motion output by the motor 30 into the linear motion of the output component 31.

[0065] The axial direction of the output shaft 301 of the motor 30 and the moving direction of the output component 31 are along the longitudinal direction Y of the lock housing 1. The output component 31 is arranged on one side of the transverse direction X of the motor 30 so that the structure of the drive device 3 and the electronic lock is compact.

[0066] The gear transmission mechanism 33 includes a worm 331, a worm wheel 332, a first cylindrical gear 333, a second cylindrical gear 334, and a third cylindrical gear 335. The worm 331 is coaxially connected to the output shaft 301 of the motor 30, for example, it is mounted on the output shaft 301, allowing it to rotate coaxially with the output shaft 301. The worm wheel 332 meshes with the worm 331. The first cylindrical gear 333 is coaxially connected to the worm wheel 332, allowing it to rotate coaxially with the worm wheel 332. The second cylindrical gear 334 meshes with the first cylindrical gear 333. The third cylindrical gear 335 is coaxially connected to the second cylindrical gear 334, allowing it to rotate coaxially with the second cylindrical gear 334. The output member 31 includes a rack portion 311, which meshes with the third cylindrical gear 335.

[0067] However, this utility model is not limited to the embodiments shown in the figures. For example, in some embodiments not shown, the type, number, and axial direction of the transmission components in the gear transmission mechanism 33 can be adjusted as needed. In some other embodiments not shown, other types of transmission mechanisms can also be used to convert the motion output by the motor 30 into the linear motion of the output component 31.

[0068] Although not shown, another exemplary embodiment of the present invention also discloses a charging dock. The charging dock includes a housing (not shown), charging terminals (not shown), and the aforementioned electronic lock. The charging terminals are disposed in the housing for mating with mating terminals (not shown) of a charging gun (not shown) inserted into the housing. The electronic lock is fixedly mounted to the housing. When the locking pin 2 of the electronic lock is moved to the locked position, the locking pin 2 is adapted to engage with a pin hole (not shown) on the charging gun to lock the charging gun to the charging dock.
